Abstract
A method and apparatus for forming a bent plate glass using a forming bed, in which a plate glass mounted on the forming bed is locally heated along a heating line whereby the plate glass is locally softened, after first heating the entire flat plate glass. The heating line is positioned offset from a desired bending line and curved outwardly therefrom whereby the heating line becomes coincident with the desired bending line due to transformation of the initial heating line as the plate glass deforms under its own weight as it is heated to softening temperature.
